A lot of things change and a lot of things stay the same, they mostly stay the same.

I'm interested in making films of all sizes. During this time I've made a film called 'The Boy in the Striped Pajamas', which is a modest-sized film. I was involved in 'I Am Legend' and 'Yes, Man', but 'Potter' is unique. There'll never be anything like 'Potter' again.

I think it's great to see how they've grown up, not just as actors but as people. They're still very much the same kids that I met many years ago. They've grown up and they are funny and wicked and naughty and bright, and I think as actors their work is just getting better and better. They've blossomed.

I look forward to having the time and the opportunity to take on new challenges, but I'm also aware that I've loved every minute of the 'Potter 'experience: to make films for an enthusiastic audience and work with great material.

I don't think you can be a director without a kind of sense of competitiveness.

In some ways, many of the skills you have as a producer on independent films also apply to making big tentpole films: You surround yourself with a brilliant director, great script and talented people in every department who are smarter than you.

The truth is, it's very hard looking back... we look at holocaust now with such knowledge and such a sense of the horror of what it was, that it's hard to believe even now that in 1930s and 1940s, before something like this had happened, that it could be impossible to imagine the extent of this horror.
